so i decided to write an article about her. after i wrote the article, i was really unnerved by thinking of a young man who had done a wonderful job as a soldier -- >> host: two tours of duty in iraq. >> guest: yes. committing suicide. and i said, this is not right. i want to know more. so i began doing a lot of research, decided -- because one of my passions in writing is human rights, and for me this is a human rights book. so i started doing a tremendous amount of research on both wars in iraq and afghanistan, and also on our veterans and their families. because who thinks of cheryl, noah's mother, and how she feels right now? you know? she said, i died too. in a way she did. and then she talked about the way noah came back, and noah had 30 to 90 days in which he could get help. what did they give him? sleeping pills. do you give a young man sleeping pills who is under tremendous stress, has nightmares, hallucinations? and how difficult it is to come back from a war situation where you're working 24/7, you don't sleep well,
